The Soviets decided that Afghanistan is a country where they have big interest to have influence and control, so they attacked it. The Soviets though did not predicted that the invasion will be so hard. The mujaheddin were Muslim followers, with radical ideology. They were not willing to let the Soviets to take over their territory, especially because it was a Christian country, so they were fighting until their last breath. These people were actually the biggest defense of Afghanistan, being able to defeat the Soviets or at least make lot of troubles in numerous battles. The US intervened as well, and they provided large amounts of weapons for the mujaheddin in order to fend of their mutual enemy, and the mujaheddin managed to do so. The US made a big mistake though, as they gave lot of weapons to an extremist group of people, and left the weapons to them after the war, as well as not monitoring their action. Later, that weapon, by the same people, was used against the US, as these people became part of the terrorist organizations.
